Waterproof DS18B20 Digital Temperature Sensor is a temperature sensor based on the DS18B20 system in a waterproof measuring probe. The module can be supplied with 3.3 ... 5 V voltage and measures the temperature in the range -55-125 ° C. Communication with the sensor takes place via a digital 1-wire interface. The sensor can return the temperature as a 9-bit value or even a 12-bit value. Each sensor has a unique 64-bit ID, which allows you to connect multiple sensors in one line. It will be used in applications that include environmental control, detecting temperatures inside buildings, devices or machines, and monitoring and controlling processes.


  • Usable temperature range: -55 to 125 ° C
  • Accuracy ± 0.5 ° C from -10 ° C to + 85 ° C
  • The choice of resolution from 9 to 12 bits
  • Uses 1-Wire interface - requires only one digital pin for communication
  • A unique 64-bit identifier
  • Many sensors can share one pin
  • Temperature limitation alarm system
  • The query time is less than 750 ms
  • 3-wire interface:
    • Type A
      • Red wire - VCC
      • Black wire - GND
      • Yellow wire - DATA
    • Type B (There are a series of sensors using this pin mapping)
      • Red wire - VCC
      • Yellow wire - GND
      • Green wire - DATA
  • Stainless steel probe with a diameter of 6 mm and a length of 35 mm
  • Diameter of the wire: 4 mm
  • Cable length: 90 cm
  • Power supply: 3-5,5 V
